HaLion 6 amp envelope

Is there any way of getting the amp envelope to work in a patch in a zone that uses a wavetable for a sound source?
I have a patch using Elegy which I need to make decay away as I hold the keys down but I can’t see how to. The amp envelope it set fine and I can see the cursor travel through the ADSR to reach zero but the sound keeps playing despite looking like it should fall silent after a few seconds

Is there anything I could try to make this happen, or is it just impossible with wavetable patches?
